Can you help me create a Proxmox cluster?

Question

Proxmox

There is a working Proxmox hypervisor, on it there are 6-7 pieces of assorted virtual machines. There is a new server. There is a wish to make a cluster from the new server and already operating. Help with the logic of this action, please. For now, I assume that you first need to set up a new node, create a cluster on it, transfer all the virtual machines to the cluster, and then add the freed machine to the cluster. Well, or poke your nose into the correct links, he did not find anything unfortunately.

Answer 1

Why do you need a cluster? Well, you control from two faces and ok

Answer 2

For a cluster, just two servers are not enough. They must be identical. They must have shared network storage, at least a couple of gigabits / s us
